I like to collect photos of naturists in action. Not just photos of nude people, or sexually oriented photos, but photos of real naturists. I think there is much to be gained from viewing real people in natural situations. Occasionally I share my collection - here is a link. I know many probably carry copyrights, so don't use them in print situations. Just enjoy.

(By the way, how did I do at gathering "real" naturist photos?)
